Some one gave me a couple of commercial kegs. Actually they are full of beer. One of Maine brewings peeper ale and one is Unitas hop nosh. After I empty them I want to refill them. I'll probably just push beer from a corny but to clean them any ideas. Hate to waste co2. Would rather just blow hot water through.

Why not just pull the clip ring on the top where the tapper goes, and pull the guts, do your cleaning, put your beer in then re-assemble? Or find a tap to sacrifice for the attatchment to the keg and rig up a way to sanitize and fill through that... Sneezles61

Sure I could but I plan on pushing beer into it from a corny bright tank and then just rinse it out after a couple uses. They don't open them to clean them at the brewery they just blow steam water through them I was thinking of doing something like that.

I can scrrw a fitting on the inlet and starch my siphon to fill also screw off the co2 valve. So filling is no problem. I just figured if I fill it with brightens beer there would be no sediment to clean out. I've pushed to uncleaned kegs before. If a 5 gallon is needed I'll push to a three gallon without cleaning it and have good success. After I open it after a couple uses its clean no sediment that was left behind.
